氧化石墨烯／奈米銀線透明導電複合薄膜製備與特性研究

A Studying for Preparation and Characterization of Graphene Oxide/Silver Nanowire Conductive Composite Film

本研究利用氧化石墨烯 （GO） 和探討GO 分散性、合成參數等，合成奈米銀線溫度、保護劑影響等，選擇導電係數較佳的配方，分析薄膜的導電性與穿透度。將合適的PMMA 含量以不同的石墨烯及奈米銀線添加量塗佈在PET 基板上製備成透明導電薄膜探討穿透度與導電性，並由SEM 觀察GO 在PMMA 的分散情形。從研究結果得知隨著石墨烯添加量導電率隨之上升，但有穿透度下降的缺點，並由掃描式電子顯微鏡 （SEM） 可以發現石墨烯添加量太多會有團聚的現象。藉由隨後添加的奈米銀線增加其薄膜導電性並保持穿透度來達成高導電高穿透的目的。塗佈在PET 基板上可以改善傳統ITO 因彎曲而產生斷裂且電阻上升的缺點。

The study use graphene oxide (GO) and silver nanowire (AgNW) andprepared transparent conductive films (TCFS) to research GO dispersion insolution and preparation condition, and silver nanowire synthesis temperatureand PVP protection agent effect. We select the best conductivity formulaanalysis the film transmittance and conductivity and different graphene andnano silver wire content with PMMA oligomer to prepare transparent con- ductive film, using SEM observation GO dispersed in PMMA. Results showgraphene content increase conductivity rise and transmittance decreased.Results also show graphene content increase conductivity rise and transmittancedecreased. We put in silver nanowire to increase film conductivityand maintain the transmittance to achieve high transmittance and highconductivity targets. Coating on PET improved the traditional ITO bentresulting in an increase in resistance.
